YouTube: Low Frequency, Loyal Base

She uploads around 1.1 videos per month, often at 7 PM EST, keeping a slow but steady rhythm. Her content here is less about trends and more about storytelling—usually in a casual, direct tone.

She isn’t focused on YouTube growth right now, but uses it for added value. Her fans use the channel when they want more time with her content.
YouTube also gives her space for possible collaborations, recap videos, or behind-the-scenes edits. While it’s not her primary platform, it serves as a backup for fans and brands alike. She may expand its use in the future depending on project demands. For now, it complements her core strategy without dominating it.

Twitch: Passive Presence

Fiorella Acosta has a Twitch account with 577.6K followers, but she has not maintained any recent activity on the platform. Her current posting rate is zero, and there are no engagement metrics available, indicating a fully dormant channel. While the account remains public, it doesn’t play a role in her current content strategy.
Despite its inactivity, Twitch still holds potential if she decides to explore live-streaming, especially for music-focused sessions or interactive Q&As. Her audience, already engaged through TikTok and Instagram, could carry over if she launches a consistent schedule. For now, the platform remains inactive and does not impact her influence score.
